Water treatment plants play a major role in the cycle of water recovery and reuse. Besides the benefits of water treatment plants, they have a great impact on the environment, social life, economy, and natural habitats. In this sense, decision-makers should effectively plan the construction and operational activities of plants, taking into account the expectations of users. Growing public expectations about water treatment plants increase the pressures on investors and government managers. In this study, we focus on defining and determining the weights of public expectations from water treatment plants and handle as a multi-criteria decision-making problem. A two-level hierarchical model is structured to evaluate public expectations from water treatment plants as model criteria. For the problem, a literature review is performed to search the main criteria. The most suitable criteria for the problem are determined using experts' opinions. Then, the sub-criteria are determined. Experts' evaluations are collected by face to face interviews. These evaluations are consolidated and finalized via the modified Delphi method. Trapezoidal Type-2 Fuzzy Analytic Hierarchy Process (T2F-AHP) is employed to determine criteria weights using results obtained by the modified Delphi method. A sensitivity analysis is performed to show the reliability of the proposed methodology. A comparison is also performed between the Analytic Hierarchy Process (AHP) and the proposed methodology. The results of this study can be used as a guide to develop public strategies about water treatment plants. Finally, conclusions and future directions of this work are given.
水处理厂在水回收和再利用循环中起着重要作用。除了水处理厂的好处外，它们对环境、社会生活、经济和自然栖息地也有很大的影响。在这个意义上，决策者应该有效地规划工厂的建设和运营活动，同时考虑用户的期望。公众对水处理厂的期望不断增长，这给投资者和政府管理者带来了压力。在本研究中，我们专注于定义和确定公众对水处理厂的期望权重，并将其作为一个多准则决策问题进行处理。构建了一个两级层次模型来评估水处理厂的公众期望作为模型标准。对于这个问题，进行了文献综述以搜索主要标准。使用专家意见确定最适合该问题的标准。然后，确定子标准。通过面对面访谈收集专家的评估意见。这些评估意见通过修正后的德尔菲法进行整合和最终确定。使用修正后的德尔菲法获得的结果，采用梯形型 2 型模糊层次分析法（T2F-AHP）确定标准权重。进行敏感性分析以显示所提出方法的可靠性。还对层次分析法（AHP）和所提出的方法进行了比较。本研究的结果可作为制定水处理厂公众策略的指南。最后，给出了本工作的结论和未来方向。
